摘要
介绍了预应力混凝土结构设计分析程序PFA的功能特点及研制过程中对若干技术问题的处理.如计入预应力轴向变形的影响,则适于计算机分析的预应力锚固损失及摩擦损失计算、预应力筋用量估算及优化、抗震设计计算考虑、施工阶段验算等.
The functions, features and some related problems of the software PFA( design and analysis program of prestressed concrete structure) are presented. These problems include the influence of prestressing axial deformation, the calculation of anchoring and frictional loss which is suitable for the analysis by computer, the estimation and optimization of the quantity of prestress tendons needed, the checking calculation of crack resistance in construction and the consideration for seismic design and calculation.
